I am the principle maintainer of GraphicsMagick, an image processing application and libraries, as well as the author of Magick++, the C++ API for ImageMagick and GraphicsMagick. Prior to spinning up the GraphicsMagick project, I helped develop ImageMagick for 5 years. I also assist with maintenance of GNU libtool, libtiff, littlecms (lcms), IJG jpeg, and TclMagick.
